Alloy Steel Button Head Socket Cap Screws

Cold Headers supplies alloy steel button head socket cap screws in a broad range of thread sizes and lengths for industrial fastening applications that benefit from a low-profile rounded head and internal hex drive.

Button head socket cap screws are commonly used in guards, access panels, machine covers, brackets, fixtures, automation equipment, conveyor systems, material-handling assemblies, packaging machinery, and other applications where reduced head projection and a smooth exposed profile are preferred. The internal hex socket provides positive tool engagement where external wrench clearance is limited.

Alloy steel construction is commonly selected for general industrial service, machinery assembly, tooling, maintenance, and equipment construction. Head diameter, head height, hex-key size, and other technical dimensions vary by nominal screw diameter and may vary slightly by manufacturer.

Our online catalog includes many commonly requested alloy steel button head socket cap screw sizes, but it does not represent every configuration Cold Headers can supply. Additional non-catalog sizes, special lengths, and difficult-to-source items may be available by request.

Description N/A

0-80 x 1/8 Alloy Steel Button Head Socket Cap Screw is used where a rounded, lower-profile head helps keep exposed hardware compact without requiring countersinking. The alloy steel construction is suited to mechanical assemblies where the drawing calls for a low-profile rounded head and internal hex drive access.

Typical applications include guards and access panels where maintenance crews can remove covers without extra external wrench clearance. It also supports automation equipment and conveyor assemblies when the compact head profile helps protect nearby moving components. Unlike a standard socket head cap screw, the button head emphasizes a lower rounded profile and broader exposed head for applications that benefit from that geometry.

For drawings using the 0-80 thread and 1/8 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below support fit checks, tool access planning, and replacement verification.

N/A

0-80 x 3/16 Alloy Steel Button Head Socket Cap Screw is commonly specified when designers need internal-hex access with a broad, finished head profile. The alloy steel construction supports machine construction where the drawing calls for reduced head projection and a socket-drive button head.

It is commonly used on control enclosures and equipment housings where the rounded head reduces sharp edges on handled surfaces. It is also suited to robotics and packaging machinery when internal hex drive access supports repeatable assembly work in tight spaces. This head style is different from a standard socket head cap screw: it trades the taller cylindrical head form for a rounded button profile used on exposed assemblies.

When matching the 0-80 thread and 3/16 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below help confirm fit, tool clearance, and replacement requirements.

Technical Highlights

  • Material: Alloy Steel
  • Thread Size: 0-80
  • Length: 3/16 in.
  • Nominal Body Diameter: #0 (.060 in.)
  • Head Diameter: 0.104-0.114 in.
  • Head Height: 0.026-0.032 in.
  • Hex-Key Size: 0.035 in.

N/A

0-80 x 1/4 Alloy Steel Button Head Socket Cap Screw supports compact fastening in assemblies where a cylindrical socket head would project farther from the surface. The alloy steel construction fits equipment assemblies where a compact rounded head profile and internal hex drive are specified.

Designers often specify it for automation equipment and conveyor assemblies where the compact head profile helps protect nearby moving components. It can also serve equipment housings and assembly fixtures when the button head presents a clean bearing surface on visible hardware. Engineers often choose this style when a standard socket head cap screw would stand taller than the assembly layout allows.

For purchasing or maintenance records calling out 0-80 thread and 1/4 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below give engineers and buyers a quick check on fit, socket access, and replacement selection.

Technical Highlights

  • Material: Alloy Steel
  • Thread Size: 0-80

N/A

0-80 x 5/16 Alloy Steel Button Head Socket Cap Screw gives equipment builders a rounded button-head form for visible or frequently handled fastening points. The alloy steel construction is appropriate for tooling applications that require a smooth exposed appearance with internal hex engagement.

This configuration is practical for machine covers and service panels where the finished head appearance is useful on exposed equipment. It also works in control enclosures and equipment housings when the rounded head reduces sharp edges on handled surfaces. The button-head form is specified when the fastener head remains visible or accessible and a smooth rounded profile is preferred.

For assemblies specified with 0-80 thread and 5/16 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below help maintenance and purchasing teams verify fit and tool access.

N/A

0-80 x 3/8 Alloy Steel Button Head Socket Cap Screw is selected for socket-drive fastening where head projection, appearance, and bearing area all matter. The alloy steel construction is used in machinery repair where a rounded head and socket-drive access help keep service work straightforward.

Suitable assembly locations include brackets, fixtures, and tooling assemblies where the broad head distributes contact over a wider seating area. The same head style is useful for brackets, fixtures, and tooling assemblies when the broad head distributes contact over a wider seating area. Selection is usually driven by head shape, socket access, and exposed-surface requirements rather than by the geometry of a standard socket head cap screw.

When checking fit for the 0-80 thread and 3/8 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below support counterbore planning, socket access, and replacement matching.
